GRATE.

SPECIFICATION forming part 0f Letters Patent NO. 436,813, dated September 23,1890.

' Application led March 20, 1890. Serial No. 344,613. (No model.)

.To all whom it may concern:

Be it known that I, JOHN TON'IZ, a citizen of the UnitedStates, residing at Girard, in the county of Crawford and State of Kansas, have inventeda new and useful Grate, of which the following is a specication.

This invention relates to grates, more particularly of that class which are adapted to be fitted to fire-places or to stoves of various sizes; and the object of the invention is to improve the construction of grates heretofore made, whereby they will be adapted to be tted as above described.

This invention consists, essentially, of a grate preferably having a dumping-section and end pieces therefor, all provided with indentations upon certain lines, whereby they may be reduced in their several dimensions from the size in which they are originally castl and yet will properly it each other.

The following specification describes and the accompanying drawings illustrate what I consider the best manner of carrying out my invention.

In the said drawings,Figure l is a plan view of my improved grate, showing the dumpingsection which is preferably employed in connection therewith. Fig. 2 is a transverse section of the same. Fig. l3 is an elevation of one of the end pieces. Fig. 4L is an end view of the grate and end piece, showing both after they have been reduced in size.

Heretofore stove-backs and back fire-walls for stoves have been provided with grooves standing at right angles to each other and along one or more edges of the back, whereby the latter could be reduced in size by break` ing italong the line of certain of said grooves, so that it could be employed in connection with a fire-place of smaller dimensions than the back as originally cast. The present invention consists in the application of thesame idea in slightly-modified form to the grate itself and to the end pieces of the fire-place, and the location 4and arrangement of the breaking lines so that the said end pieces will fit upon and be interlocked with the grate,

' even after they have been reduced in size.

of the grate stand preferably forward and back beneath the fire-place and their rear ends are connected byaback barB. In rear of this back bar is a number of parallel supplemental bars S, slightly spaced, as shown, and the gratebars are extended in rear of the back bars across the supplemental bars to connect them with the body of the grate. However, the 6o depth or size of the grate-bars in rear of the back bar is much less than forward thereof, for a purpose to appear farther on.

E are the end pieces, approximately of the shape shown, which are formed separately from the grate, and each piece has a curved front edge approximating the curvature C of the upper front bar of the grate. The .lower edge of the end piece has a shoulder S', adapted to rest in front of the back bar B 7o when the end piece is in place, and the body of the latter in rear of said shoulder rests upon said back bar and upon the supplemental bars.

The grate G is provided in its upper face along the outer edges of each of its bars with indentations I, whereby one or more of said bars may be removed from the ends of the ugrate in order to adapt it to iit into a stove or a lire-place of a certain length. In this case it will beunderstood, of course, that the end pieces are moved farther inward and normally rest against the ends of such fire-place.

In order to accommodate the grate to fireplaces of less width, one or more of the supplemental bars S may be broken away atpoints where the reduced grate-bars connect them with each other and with the back bar, and in this case the end pieces, which are provided at proper points with similar indentations I near their edges, are reduced in width by breaking away on one of the lines t' near the front edge thereof; or, when the back of the fire-place inclines forwardly, the end pieces may be broken on one of the lines t" and the grate proper can be reduced in width to the necessary extent in the manner described above. In order to accommodate the end pieces to fire-places of less depth, I provide them with a series of indentations I which stand parallel with the `lower edge thereof. Longitudinal lines Z of indentations may be formed near the upper front corners of the grate, about as shown, whereby these corners or portions thereof may be broken away when necessary to fit the grate into stoves which would require it.

What I claim is- 1. The herein-described grate, comprising front and back bars and supplemental bars in rear of the latter, connected thereto by breakable extensions, and the grate-bars connecting said other bars, said front bar, back bar, and supplemental bars being provided with breaking indentations in atransvers'e line with the outer side of each grate-bar, as and for' the purpose set forth.

2. The combination, with the grate com prising front and back bars, the supplemental bars in rear of the latter conn ected thereto by y With said breakable extensions, as and for lthe purpose set forth.

In testimony that I claim the foregoing as lnyown I have hereto affixed my signature 1n presence of two Witnesses.
